摘要： According to some embodiments, a method is performed by a wireless device for transmitting uplink data. The method comprises determining a predetermined configuration according to which to transmit uplink data and one or more repetitions of the uplink data. The method further comprises determining a cyclic shift for one or more reference signals transmitted with the uplink data and the one or more repetitions of the uplink data. The method further comprises transmitting the uplink data, the one or more repetitions, and the one or more references signals to a network node. The uplink data and the one or more repetitions are transmitted according to the predetermined configuration. The one or more references signals are transmitted according to the cyclic shift.

摘要： There is disclosed a method of operating a radio node in a Radio Access Network, RAN. The method includes transmitting acknowledgement signaling pertaining to at least two transmission data streams in which the acknowledgement signaling is determined based on performing a combined error evaluation pertaining to the at least two transmission data streams based on a combination indication obtained by the radio node. The present disclosure also pertains to related methods and devices.

摘要： Systems and methods for determining and utilizing downlink Hybrid Automatic Repeat Request (HARQ) timing when using short Transmit Time Intervals (sTTIs) are disclosed. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises determining a downlink HARQ timing k for transmission of downlink HARQ feedback for a downlink transmission received in a downlink sTTI nDL based on a Time Division Duplexing (TDD) uplink/downlink configuration and transmitting, in an uplink sTTI nDL+k, downlink HARQ feedback for the downlink transmission received in the downlink sTTI nDL. In this manner, downlink HARQ timing is determined and utilized when using sTTIs.

摘要： A method for retransmission of uplink transmissions, performed by a wireless device with configured uplink grants. The method comprises transmitting a first transmission to a network node with a redundancy version (RV). The wireless device then determines to retransmit the first transmission, and retransmits the first transmission with a retransmission RV based on the type of retransmission. For a non-adaptive retransmission, the retransmission RV value is the same as the RV of the first retransmission. For an adaptive retransmission, the retransmission RV is the RV value received in a retransmission grant.

摘要： A first Wireless Local Area Network (WLAN) node and a method therein for performing a transmission to a second WLAN node in a WLAN. The first WLAN node identifies a third WLAN node transmitting a first signal (S1) overheard by the first WLAN node, and determines to transmit, to the second WLAN node, a second signal (S2) based on the identity of the third WLAN node and on a received power of the first signal. When determined to transmit the second signal, the first WLAN node determines a Modulation and Coding Scheme (MCS) index value by means of a link adaptation process specific for the identified third WLAN node and transmits to the second WLAN node, the second signal using the determined MCS index.

摘要： The present disclosure relates to a technique of supporting access to a wireless medium of a wireless communication network. A method embodiment comprises: when access of a station (100) to the wireless medium is delayed, determining (S202; S308), by the station, a back-off period indicating the period of time the access of the station to the wireless Determine back-off medium is delayed, and entering (S204; S312), by the station (100), into a sleep mode for a sleep period based on the determined back-off period.
